A U.S. federal appeals court on Wednesday tossed a $533 million verdict in favor of patent holder Smartflash, which in an earlier court battle had argued that Apple violated its data storage concepts by way of iTunes.

A Texas federal judge has refused to grant Apple a new trial in its fight against a Smartflash patent infringement lawsuit, but simultaneously declined to reconsider a decision to toss $532.9 million in damages that were originally awarded to Smartflash.

On Thursday, the U.S. Court of Appeals for the Federal Circuit refused to stay proceedings in Smartflash's patent lawsuit against Apple, potentially paving the way for Smartflash claiming recalculated damages.

Samsung has asked the US Patent and Trademark Office to review two Smartflash patents, a move that could potentially absolve Apple of paying $532.9 million in damages following a Smartflash court victory in February.
